If they are 6"w rims then 0 offset would be 3.5"BS which is what I need! When you get a chance that Will be super helpful.
I am planning on going to the guys house in swapping out the wheels right before I drive across the border, so if I need spacers will need to have those on hand ahead of time. Many thanks!
Confirmed, they are zero offset! Not sure how I missed it earlier.
